Description

In an automated plant 80 % of faults during operation are process faults. Your diagnostics are plant-specific and cannot therefore be integrated into the controller hardware or firmware. Instead, this must be programmed. To keep related costs low, the use of diagnostics tools is recommended.
Process diagnostics support maintenance personnel with troubleshooting and fault avoidance:
